*** F@H Tech Assistance Thread ***

Yup thanks I was looking for that. I've done everything he says to do and it still won't show any core utilization for GPU 1. I still have it fold though. Maybe its cause I can't exit Crossfire.

Just to verify:
You have a GPU F@H client installed in 2 different directories.
You have different machine ID's for each client.
You setup 2 shortcuts to the 2 clients.
You're using the -gpu 0 and -gpu 1 argument.

There is a forum at Stanford for ATI issues, especially the X2 cards.
Here's what one person says: -forcegpu ati_r600 -gpu 1

With regards to 2 GPU's, SLI enabled, and no dummy plugs.......I have mine with no issues

what does -local do?

what does -local do?

"
-local
Use configuration files from local directory. This option has no meaning on Linux, but is vital on Windows and Macintosh for running multiple clients on a machine. It instructs the client to read its config information from the client.cfg file in the current directory rather than, on Windows, from the installation directory specified in the registry, or, on Macintosh, the Library/Folding@home directory. Information such as the user name, team name, proxy information, machine ID are maintained in the client.cfg file. The flag ensures that work does not conflict. Use "-local" only if you are planning on running more than one instance of Folding@Home on the same machine (this is only useful if you are running on a multi-processor machine). Create as many directories as there are processors on the machine, copy the exe files and client.cfg file into each of these directories, run "FAH3Console -local -config" on each and specify unique machine IDs for each directory (under the Advanced Settings option). From then onwards you may run each copy by switching to its directory and running with the -local flag."

Dummy plug worked to get the 3rd card running. For some reason only the 3rd card needs the dummy plug, as #2 just starts with no dummy plug no issues.

 

[Wile E]

Finally got around to making a dummy plug. I now have both cores of the 4870X2 running and my last remaining Palit 8800GT using the gpu console versions. I also got the ps3 up and running.

I figured if I'm gonna see how this effects my electricity bill, I might as well go all out, and check the worst case scenario, and scale back as needed.

Now, how in the hell do I hide those damn f@h icons in my task bar? lol

Congratulations on getting them all up and running. I'd like to see what the daily output from your X2.

Guys,

I am facing this weird issue on one of my new builds for my friend.

He got one Zotac 9800GT and he bought 2 xfx 9600GSOs. I setup 3 nvidia clients as per the post. He has installed win7 64 bit on the new rig. I had read on the HCN post tht on win7 we can run multiple clients with the -advmethods -forcegpu nvidia_g80 flag without using any dummy plug.

Two of the three cards run. But the third card gives EUE. I changed the slots. But its always one that gives EUEs. Before only the 9800GT was EUEing. After I changed the slots, its one of the GSOs thts EUEing.

I installed the latest 191.07 drivers. By the way the mobo is Asus WS Reveloution which has 6 PCIe slots loaded with latest bios.

Guys,

I downloaded the new FAH 11 and 14 cores and also used a dummy plug for the card that was not folding as per Buck's instructions. But 2 out of 3 cards folded. The third one was still giving unstable machine error. Then I made two more dummy plugs and put them to the other two cards. Rebooted the machine and Windows 7 automatically had extended my desktop to 3 displays.

Tried the 3 clients. ALL of them are folding now!!

Thanks El, Bogi, Buck and all our mates!!

Cheers,
Shiv

Update:
Got my 2 GSO's working at the same time on 1888 pt WU's! I changed 2 things so I don't know which is the fix. Although I see the value of trying to figure out which is the fix, I just don't want to spend the time to figure it out.
1.)I turned off SLI.
2,)Added -forcegpu nvidia_g80 in for GPU-0. When I set these up, I couldn't get GPU-1 to work and I was forced to use the -forcegpu nvidia_g80 for GPU-1, but not for GPU-0. I did not modify GPU-0 at that time.

Question/conclusion: Will the amount of problems we have be reduced by having more specific command line parameters to tell the client exactly what we want it to do instead of letting it figure it out for itself?

 

[El Fiendo]

Very weird. I set my 3x GTX260 rig up again yesterday. I enabled SLI, PhysX enabled. The flags in use are -gpu 'X', (where X is from 0-2) and -forcegpu nvidia_g80. I don't have the -local flag, or the -advmethods flag currently set though I'll try adding both tonight to see if they break anything.

At this point all 3 are up and running at 100% of expected speeds. I can't figure out what's going wrong with your setups.

 

[mstenholm]

Can anyone tell me how I can do what this guy is doing?
http://folding.extremeoverclocking.com/user_summary.php?s=&u=469043
120,530 points for 5 WUs.

 

[El Fiendo]

I believe he's currently doing the '-bigadv' thing that requires 8 physical cores or an OC'ed i7 920 with virtual cores enabled.

At least that's what I assume. It's also what i want to get into.

How much memory would that require?

You mean it's nescessary to overclock an i7 to do one of these huge work units?

 

[El Fiendo]

I believe they have to be OC'ed to get the WUs in before the time limit, yes. Or so I recalled reading anyways. I'm actually surprised to see they're allowed on i7 rigs. It used to be that only Macs and Linux could run this as they were the only ones that usually had the cores to do it. And because i7's '8' cores is weaker than a real 8 cores I could see it needing a little help to do this monster.

The guide I read recommends dedicating 5 GB of memory to the VM running the -bigadv work unit, Wile E.

 

[[Ion]]

I believe so, I think I read at XS that a 2.8ghz i7 will complete the WUs just in time if folding exclusively, but receive no bonuses. Anything past that gets bonuses, or can afford down time

i need help....
I got my 2nd 8800GT today. It works fine on its own. I put the other 8800GT(also works fine) in it and only one of them works. The one in the primary slot works fine. The one in the slave slot isn't even seen. I have tried everything i can think of in the bios and even tried different drivers. I'm not trying to SLI them so thats not the problem...

OS is win.7 32bit all the other specs can be seen in my specs. please help me

New Nvidia drivers produce terrible PPD?

I just installed the new Nvidia drivers last night and I seem to be getting terrible PPD. F@Hmon reports just under 700PPD on a 472pt work unit (project 5906). Is this normal? This is on an overclocked 9600GSO (96 shader model).

thats not normal at all. My 8800GTS(g80 96 shaders) gets around 4.2k PPD on those WUs

 

[hertz9753]

That would be about right for a GTX 260. 472 WU's suck, they about the same ppd as as the 1880's, but run alot hotter.

mine or his? he is saying 700ppd i am saying about 4200ppd. If your GTX is getting that low of points then you do have a problem to work out

My bad, I read it as 7,000 ppd.

 

[El Fiendo]

Ah ha! I've weeded out another problem. This is starting to feel like a wild goose chase trying to find all these ghosts in the machine.

Anyways, to everyone who was having trouble getting their cards to fold without dummy plugs, I recently discovered my third card was doing nothing but spitting EUEs after the last shutdown. I couldn't explain it but I was mirroring the same issues posted by others here, 2 cards would work but the third wouldn't. I then noticed that I'd accidentally left the 3-Way SLI bridge off, when it had been on beforehand. After reinstalling the bridge and restarting all the clients, my issues were resolved.

So, it appears that the guide is correct that you don't need an SLI bridge, but this is only true for 2 card situations. My 3rd card started folding correctly as soon as I added it back in.

Hopefully this helps, if anyone is still currently struggling with this.
